Abstract
To update firmware on a consumer device intelligently, two or more application images are stored as firmware on the consumer device. If the primary application image is corrupt, the back-up application image is executed on the consumer device. The back-up application image can be updated based on the primary application image. User configuration files can be preserved during the update of an application image, or they can be overwritten. This firmware updating scheme can be advantageously implemented in a personal media broadcasting system.
